21 Some of the lanes are high-speed lanes, which can be used for PCIe, SATA or
22 super-speed USB. Other lanes are for various types of low-speed, full-speed
23 or high-speed USB (such as UTMI, ULPI and HSIC). The XUSB pad controller
24 contains a software-configurable mux that sits between the I/O controller
27 In addition to per-lane configuration, USB 3.0 ports may require additional
28 settings on a per-board basis.
30 Pads will be represented as children of the top-level XUSB pad controller
33 PHY bindings, as described by the phy-bindings.txt file in this directory.
37 "port" is typically used to denote the physical USB receptacle. The device
38 tree binding in this document uses the term "port" to refer to the logical
39 abstraction of the signals that are routed to a USB receptacle (i.e. a PHY
40 for the USB signal, the VBUS power supply, the USB 2.0 companion port for
41 USB 3.0 receptacles, ...).

223 Each port may need additional resources that can be referenced in its
224 port node.
226 The "status" property is used to enable or disable the use of a port.
227 If set to "disabled", the port will not be used on the given board. In
228 order to use the port, this property must be set to "okay".
